Books by Russell Brand, Noah Levine, Dr Gabor Mate, James Frey, Carlton Erickson Ph.D and Mackenzie Phillips joined mine on the list of the 42 Best Drug Addiction Books of All Time, so I'm in pretty good company!

And it's not one of those "fake awards" that you pay to enter or receive your award. I didn't even know I'd won until I was notified.

BookAuthority collects and ranks the best books in the world, based on dozens of different signals, including public mentions, recommendations, ratings, sentiment, popularity and sales history. The website has been featured on CNN, Forbes and Inc.

People who recommended books for the list included Demi Lovato and James Altucher.

It really is humbling to get this kind of recognition. After all, I'm just a recovering alcoholic who wanted to help others find a recovery as happy as mine has been.

But it's also an honour to know that my book has touched and helped so many people.

If you've ever bought, recommended or rated The Happy Addict, then you are a huge part of this wonderful achievement, and I want to thank you from the bottom of my heart for your support.

If you haven't yet read The Happy Addict, you can order it from most bookstores or buy it online at your favourite online bookstore, including Amazon.com and Amazon.co.uk.
